Front Passenger Side Door Entry Lock and Unlock Functions do not Operate [10/2018 - ]: Description

If the entry lock and unlock functions do not operate for the front passenger door only, the request code may not be being transmitted from the front passenger door or the front door outside handle assembly RH (touch sensor) may be malfunctioning. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and electrical key and TPMS receiver assembly is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and front door outside handle assembly RH (electrical key antenna)), or there may be wave interference.
